Myl invention relates to reinforcements i and particularly to means for holdinga series of crossedreinforcing rods in spaced relation.V f*

In sometypes 'of constructlomutis desir` able to assemble the reinforcement before placing it inpositiomand numerous expedients have been adopted "for accomplishingv the desired result VIn the construetionhere disclosed I have. provided a'simple device having noloose or separate Vparts and func# tioning to space apart two layers of reinforcement and. to holdfthe crossed bars in.,

rigid relation. VThe rdeviceconsists essentially of a rigid -member having af crotch at each. end and arms or ngersformed as eX-pv tensions of the.,crotch'armsandnadapted tovv T overlie and underlie, respectively apair ofi.

, yI claim:

,1. Incombination a pair Ofrwires interlengaged at their intermediate portions @to form a rigid Vspacing structure having .a fcrotch for receiving a bar, ,the end' portions ofthe wires being bent to provide spring arms having hooks on theirends, said arm beingv adapted tooverlie acrossed bar and to engage at their ends beneathfthe first men- I i tioned bar.

-2. In combination, arpair of wires interen` lgaged at their intermediate portions to form a rigidspacing structure, having a crotch at bothendsfor receiving parallel spaced bars,

of springv arms adapted to overlie crossed -bars,.theterminals of the arms being 'provide Ved. with hooks to underlie the first .men-f tioned bars.
